Title: Construction method of underground pipeline and underground pipeline constructing device
Inventor: HASEGAWA SUSUMU
IPC: E21D9/06
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To attain construction of safery and high efficiency by providing a film cartridge arranged in front of an underground pipe and diliverably receiving a film covering the outside of the underground pipe, and a lubricant injection means injecting lubricant into a gap between the film and the underground pipe. SOLUTION: A lubricant injection pump 17 is operated to inject lubricant into the gap between a film covering the outside of an underground pipe 3a and the underground pipe 3a, and inject from the front and the rear of the underground pipe 3a through a primary injection pipe 14 and a secondary injection pipe 15. At this time, to an underground pipe sent from a shaft 7, lubricant is supplied immediately and continuously, and the gap between the underground pipe 3 and the film 4 is filled with lubricant to form a lubricant layer. In this case, after the hydraulic cylinders 8 of a press-in device 2 are sufficiently extended, the cylinders 8 are again retreated, a next underground pipe 3b is set in the press-in device 2, and joined to the rear end of the underground pipe 3a.  Hereafter, the underground pipe 3 is propelled by the press-in device 2 while joining together, and after completing the work, an opening/ closing valve is closed to backfill a groove hole. Hereby, the lubricant layer is completly sealed to prevent the lubricant from leaking to the outside.

Title: Erasing system of magnetic disk
Inventor: SAITOU ETSUROU
IPC: G11B5/024
Filed: 1984-06-14
Abstract: PURPOSE:To erase from low frequency component to high frequency component without lowering rotational frequency of a magnetic disk by setting initial frequency in the frequency band of a record signal and recording alternating signals that change gradually until becoming higher than upper limit frequency and erasing. CONSTITUTION:When erasing a recorded still picture, a switch 9 is changed, and a signal of a sweep generator 8 is supplied to a magnetic head 3 through a recording amplifier 6. The sweep generator 8 is made variable by a counter 7 that counts rotational frequency of a motor 2, and frequency of an erasing signal increases with time. In this initial stage of sweep, recording magnetic field of the magnetic disk 1 which is in low band frequency area is rewritten and erased by initial frequency of sweep. As the sweep frequency becomes higher, the high band recording magnetic field is successively rewritten and erased by the sweep frequency. Finally, only the recording magnetic field due to final frequency set outside of recording frequency band remains, and consequently, the recorded still picture information is erased.

Filed: 1980-09-03
Abstract: PURPOSE: To provide a cooker having a magnetron and a heat source like a gas burner, which is designed to be capable of protecting the magnetron against hot air discharged from a vent hole, by disposing the magnetron at a position lower than the vent hole.  
     CONSTITUTION: In case of performing scorched cooking through high-frequency heating by a magnetron 4 and a heat source 5, a cooling fan 8 and a circulating fan 6 are both set into operation to increase the internal pressure of a heating chamber 2 and to reduce the amount of air supplied into the heating chamber 2 by the fan 8 to a great extent. Here, it is desirable to reduce the supply of air into the heating chamber 2 almost to zero. If supply of air is reduced excessively and hot air is discharged from vent hole 10, it is discharged frorm an opening 12 of a duct 11. Further, back-flow of hot air into the duct 11 is prevented since magnetron 4 is disposed lower than the vent hole 10. Thus, it is enabled to protect the magnetron 4 against heat of the hot air.
